At the moment it's worse: a fixed table in client/gui-*/colors.c.

Wouldn't it be possible to traverse the colour space in a systematic
manner?  Define a distance function between any two colours, eg.

int colordistance (int red1,blue1,green1,  red2,blue2,green2)
{
  return int(red1-red2)+int(blue1-blue2)+int(green1-green2));
}

and iterate in such a way that the next colour picked is always
at maximal distance to all the previous colours.

Some reserved colours (black, sea blue, grass green)
would be picked in advance.

Yes.  The distance notion would be needed here to decide
if a colour is acceptable.

Not necessarily, if the colour remapping is part of the client-side options
(not tied to a game, but to a client).
